Specification forming part of Letters 'RaitentNo. 2225 4355; dated tDecenrherit), 1879:; application :filetl August 27, 1879'.

To all whom it may concern:

Be it known that I, Fnnnnnrcx HELLER, of Newark, in the county of Essex'and State of New Jersey, have invented a new and useof the beer, and in any weather'makin g it liable to take up impurities from the air, which 1 spoil or impair it by causing what is known as foul fermentation.

The invention consists in the combination, with the exterior pipes and connections, of interior pipe-sections, formed into a cluster of pipes by solid heads made to fit the inner diameter of the exterior pipes and theircoupled connections; and in the combination, with the inlet and outlet pipes, of test-tubes inserted through their sides, as will be hereinafter described and claimed.

In the accompanying drawings, on Sheet 1, Figure 1 represents a side elevation of my improved beer-cooling apparatus, parts being broken out to show the interior. Figs. 2, 3, and 4 are detail cross-sections of the same, taken through the lines a, y y, and z 2, respectively. Fig. 5 is a crossrsection of a nest of the interior or beer pipe removed from the exterior or water pipe. In (at 2, Fig. 6 is a side view of a portion of the apparatus, partly broken out to show the construction of the expansion-joint for the beerpipes.

Similar letters of reference indicate correspondin g parts in the several figures.

The pipe-sections A are 'secu-red at suitable distances apart and at a slight inclination to the horizontal, in the manner of an ordinary steam-heating coil, to a supporting-frame or brackets, A, and their ends are openfor the convenient insertion in each section A of a pipe or nest of pipes, G, (slightly longer than the exterior pipe,) through which the warm beer is allowed to flow in the direction indicated by arrows 2. For this purpose the continuity of the interior beer-conductor is formed by curved pipesD joining alternate ends of the interior pipe-sections, 0, each pipe D being provided at each end with a flange, d, tightened by an ordinary coupling-nut, d, screwed upon the threaded end of the pipe A.

The pipes c of each interior section, 0, are held together (with suitable spaces intervening for the circulation of water around them) by having their ends tightly secured in holes in a plate, disk, or other solid, E, fitting the interior cross-section of the outer pipe, A.

A packing-ring, F, surrounds the extreme solid end E of the inner section, 0, in position to be interposed and compressed between the flange d and the end of the pipe A, thereby expanding diametrically, and thus forming a water-tight joint, to prevent the water in the outer pipe, A, from mixing with the beer in the pipes c of the inner pipe-section, O.

The nipples G G, which form the inlet and outlet connections for the beer-pipe, are attached and packed in precisely the same manner as that just above described. The flanged end of pipes D G G should be of the same interior diameter as the pipe A, in order that it also may surround the head E of the nest of interior pipes, O, as shown in Fig. 6, and thus allow the latter (which are preferably made of copper) to expand and contract freely, accord ing to the variations in temperature, while maintaining the tightness of the joint. Into each of the nipples B B G G is inserted through the side a short pipe, H, closed at its lower end. These are filled with water to serve as test-tubes for ascertaining the temperature and diflerences in temperature of and between the water and the beer at their respective points of inlet and outlet to and from the apparatus, which is done by inserting a thermometer in each tube H. By this construction the interior pipe-sections, 0, present a large area to the cooling action of the water, thereby gaining more rapid effect, which is, furthermore, secured by the water being forced upward, and thus compelled to always keep the pipes A full, while the passing volume of the down-flowing beer is at any time comparatively small to that of the cold water.

It is evident that by this apparatus the beer (being always cooled while within the pipes immersed in water) is never liable to foul fermentation caused by contact with the outer air.

By passing steam through the outer pipe and through the inner pipe (the feed-water to be used for making beer) this apparatus may be used as a heater for the latter, if desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The interior pipe-sections,0, each formed pose set forth.
